Problems solved by technology

At present, when designing single-polarization indoor distributed antennas, conical structures are often used to achieve vertical polarization. However, the existing single-cone structures are difficult to achieve a wide bandwidth of 136.4% (0.70GHz) covering 2G / 3G / LTE / 5G frequency bands. -3.7GHz), and it is difficult to maintain good omnidirectional radiation characteristics of the antenna while achieving a wide bandwidth of the antenna

Abstract

A single-polarization low-out-of-roundness indoor distribution antenna comprises a top radiation unit, a vertical polarization radiation unit and a grounding plate. The vertical polarization radiation unit comprises a plurality of radiation patches which are distributed in a circumferential array by taking the center of the grounding plate as a circle center, and each radiation patch is arranged in an extending manner along the vertical direction; the outer side of each radiation patch is provided with at least one notch; the top radiation unit comprises a first circular patch and a second circular patch which are arranged up and down; by means of the six radiation patches distributed in the circumferential array, the out-of-roundness of the antenna is improved while the high-gain radiation characteristic of the antenna is maintained, and the frequency resonance points of the antenna are increased and the bandwidth is expanded by forming the two notches in the radiation patches; the out-of-roundness of vertical polarization radiation is improved through the first circular patch and the second circular patch which are arranged at an interval; impedance matching of the antenna is improved through the arc-shaped hole of the grounding plate, and good omnidirectional radiation characteristics of the antenna are maintained.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a single-polarization and low out-of-roundness indoor distribution antenna. Background technique [0002] Indoor communication is the main scene of daily life communication. The indoor antenna system can provide signal source and sink for indoor communication to transmit signals. Therefore, the development of indoor distributed antennas that simultaneously cover 2G / 3G / LTE / 5G frequency bands has broad application prospects. Generally, each sink in an indoor scene is required to receive good signals, which requires indoor distributed antennas to have better omnidirectional radiation characteristics and better out-of-roundness in the XOY plane. At present, when designing single-polarization indoor distributed antennas, conical structures are often used to achieve vertical polarization. However, the existing single-cone structures are difficult to achieve a wide bandwidth of 136.4%...
